Scientists put forward a simple new way of counting microscopic particles in optical materials. A laser beam passing through such a material splits and forms a pattern of numerous bright spots on a ...

Analyzing microplastics (MPs) in real environmental matrices requires the unambiguous identification of particles to distinguish them from particles of biogenic origin, such as particulate organic ...

A PHOTO-ELECTRIC apparatus for counting individual microscopic cells in fluid suspension has been constructed in this laboratory. A sufficiently large signal-to-noise ratio from a single cell or a ...

(Nanowerk News) Scientists from Russia and Australia have put forward a simple new way of counting microscopic particles in optical materials by means of a laser. A light beam passing through such a ...
